Where it fits for triathletes

The points below are our reading of the listed features, not test results.

  • Run-focused. Garmin positions it as a running watch, so a triathlete who wants full multisport features should compare it with the Forerunner 970 before buying.
  • Battery. 19 hours of GPS covers most race distances up to a half-iron, but check the figure against your slowest expected finish.
